During a studio session, markups are locked in place. Often it is needed to see the original text behind a markup.
The current workflow to do this involves saving the document and removing the mark up on a local copy which is time consuming and cumbersome.
Adding an option to see the underlying text would make the user interface feel more polished and reduce frustration.
This option could be implemented similar to the "show desktop" button on windows machine, where markups are hidden on the client while the button is hovered over.
